Stiffened structure including an opening

The structure (10) has nodes (12) in which a set of stiffeners (14.1-14.3) of different directions intersects with each other. Surfaces of the set of stiffeners are arranged in planes. An opening (26) is surrounded by a hexagonal belt that is formed by peripheral stiffeners (40). Secondary stiffener...

Zusammenfassung:The structure (10) has nodes (12) in which a set of stiffeners (14.1-14.3) of different directions intersects with each other. Surfaces of the set of stiffeners are arranged in planes. An opening (26) is surrounded by a hexagonal belt that is formed by peripheral stiffeners (40). Secondary stiffeners (44) are aligned with the set of stiffeners. The secondary stiffeners have the same cross-section as the peripheral stiffeners. Connecting units e.g. bolts, are arranged between the opening and the hexagonal belt.
